IMPROVEMENT IN RING -SPINNING FRAMES.

Specification forming part of Letters Patent N0. 217.389, dated July 8,1879; application filed March 1, 1879.

To all whom it may concern Be it known that I, EDWIN T. LANPHEAR, ofPhenix, in the county of Kent and State of Rhode Island, have inventedcertain new and useful Improvements in Ring- Spinning Frames, of whichthe following is a full, clear,

each successive traverse, and mechanism for independently operating thering-rail to give to it the traverse motion, and the spindles to givethem their separate building movement, whereby a widely-varying andextreme strain upon the yarn, consequent upon a varied and extendeddistance of the ring-rail from the drawing-rollers, is avoided, andthere is no obiectionable lifting of the spindles and their rails ateach end of the traverse, but only a lifting of the spindles and railsat the end of each complete building movement, and a proper relativeautomatic traverse motion'and building movement are obtained.

The invention also consists in a combination, with the rising andfalling ring-rails and longitudinally moving and rotatingcop or bobbinspindles, of rock-shafts having arms or lifters for lifting the ringrails, and rocking sleeves or shells arranged to encompass or receivewithin them said rock-shafts, and mechanism for imparting to saidrock-shafts and sleeves the necessaryreciprocating movement, and wherebythe raising and lowering of said spindles and their rails is effected.

In the accompanying drawings, Figure 1 represents a sectional endelevation of a ringspinning frame, in part, having my invention applied;Fig. 2, a horizontal section of the same on the line w m,- Fig. 3, apartly-sectional side view thereof, and Fig. 4 a vertical section of thesame on the line 51 y in Fig. 1.

In said drawings only such parts of a ringspinning frame are shown asare necessary to explain my invention. The drawing-rollers, which mayoccupy the usual position, and the usual or any suitable devices forapproximately counterbalancing the spindles carrying the cops orbobbins, and the rails which support and guide said spindles, the,ringtravelers, and various other devices not necessary here to beshown, are omitted.

A represents the main frame, and B B the ring-rails, of a ring-spinningframe. 0 O are the spindles which carry the cops or oneheaded bobbins,on which the yarn is wound in cone-shaped layers. D D are the guiderailsof the spindles, and E E the step-rails thereof, both of which rails andtheir spindles are suitably balanced, or nearly so.

G is a main driving-shaft, on which is a conical or tapering pulley, H,that serves to give motion, by means of a reversely-tapering pulley, I,and band b, to a shaft, J, on the outer end of which is a spur-wheel, c,which gears with a spur-Wheel,d,on ashaft, K. This shaft K carries adrum, L, by which and a corre sponding drum, L, arranged in parallelrelation with it, and bands 0 0, arranged in suitable relation with thedrums L L, and with elongated whirls upon the spindles 0 O on both oropposite sides of the machine, said spindles are rotated.

Upon the shaft G'IS a screw, j, which serves to give motion to aworm-wheel, g, upon a shaft, M, which is here shown to occupy an obliqueposition relatively to the horizon. This shaft M gears by abevel-pinion, h, with a bevel-wheel, i, upon a shaft, N which carries aspirally-grooved cam, 76, that by means of a belt-shifter, which mayconsist of a lever, O,

and sliding double fork P, serves to shift the band I) along thetapering pulleys H I to vary the speed of the spindles O O, tocompensate for the variations in diameter of the cone- 7 shaped layerson the bobbins or spindles, and so to insure a uniform draft and twist;but this forms no part of the present invention.

The ring-rails B B, which only move up and down the length of thetraverse, are operated in timely relation with the alternatelyincreasing and diminishing rotary'motion of the spindles, which takesplace as the cone-shaped layers increase or diminish in diameter bymeans of a heart or other suitably shaped cam, Q, on the shaft N. Thusthe ring rails B, which are free tofall by weigh t, rest, by means ofguide-rods k, on lifters I, attached to a pair or series of rockingshells or sleeves, R 1%, arranged alongand over parallel rock-shafts SS, and are connected, by means of arms m, fast to said shells andconnecting-rods n, so as to move in concert. Fastto one of these shellsR is an arm, T, which is attached bya rod, 8, to a lever, T, which hasits fulcrum at u, and rests at its one end on the cam Q, so that as saidcam is rotated by the shaft N it serves to give the lift to and controlthe drop of the ring-rails B B to an extent or length of movement whichis equal to the traverse, and in timely relation with the alternatelyaccelerating and diminishing rotary motions of the spindles O (J.

The rock-shafts S S, which. are connected by arms a and rods b to movein concert, and are provided with lifters c, on which the rails carryingthe spindles G 0 rest by means of rods d, attached to the step orbolster rails I 1 llfserve to control the longitudinal or buildingmovements of the spindles. Said shafts S S are operated or have theirmotion controlled for this purpose by an independent shaft, A, on whichis a heart or other suitably shaped cam, B, that when the shaft A issuitably turned acts against an arm, 0, at tached to the one'roclrshaft,S, and raises the spindles O G and their rails D E to their greatestelevation for starting on the building movement. This may be done byhand by turi'ling the. shaft A till the highest point of the cam 13passes from under the arm 0, after which the spindles and their railsare free to drop by any suitable controlling mechanism the thickness ofa layer at each end of the traverse motion effected by the up-and-downmovement of the ring-rail, a pawl, f, on the end of the lever '1, andarranged to engage with a ratchet-wheel g on the shaft A, being used, ifdesired, to control the movement of the cam B. Thus the longitudinalmotion of the spindles O O is restricted to the building of the cop, andit is unnecessary to lift the spindles at everytraverse, which liftingof the spindles and their rails, although said devices are apone withinthe other, insures great compactv ness of the devices for giving thenecessary traverse and building movements, respectively,

to the ring-rails and spindles carrying the cops or bobbins.

' I claim- 1. The combination, in a ring-spinning frame having atraverse mechanism to wind the yarn in cone-shaped layers, of aring-rail having a risin g-and-fallin g motion equal to the traverse,spindles having a downward-building movement at the end of eachsuccessive traverse, and mechanism for independently operating thering-rail to give to it the traverse motion, and the spindles to givethem their separate building movement, substantially as and for thepurpose or purposes specified.

2. The combination, with the rising and falling ring-rails andlongitudinally moving and rotating cop or bobbin spindles, ofrock-shafts having arms or lifters for lifting the ring-rails, androcking sleeves or shells arranged to encompass or receive within themsaid rockshafts, and mechanism for imparting to said rock-shafts andsleeves the necessary reciprocating movement, whereby the raising andlowering of said spindles and their rails is effected, essentially asdescribed.
